Question

Why is the boiling point of ethyl alcohol is more than dimethyl ether?

Answer 1

There's Hydrogen bonding in alcohol while there's no such bonding in ether.

Answer 2

Because hydrogen bonds are typically much stronger attractions than ordinary dipole moments, a group of ethanol molecules is much harder to separate from each other than a group of dimethyl ether molecules. The ethanol has a much higher boiling point. ... In an alcohol, there is an OH group attached to a carbon.
